Added some error checking when loading maps
Nicer graphical user input and error messages
Added prompt for images folder to load tiles/sheets from
Increased the number tiles in the selection part to 100 tiles (5 columns of 20)
Changed screen size to 1366x768
Changed program name to "Tile map editor"
Now has the map codes feature added initially only 6 hard coded codes, to put the map code on the map click the mode button to change to mode 1 then click the w button then click on the map, to clear a code click the X button then click on the map click the mode button again to switch back to tile mode.
When you save a map it creates an additional file containing the map codes prefixed with "MapCodes-". Load will look for a map codes file and load it automatically.
Will probably be the last update for a few days as I will be switching to creating a game (Using the tile map editor).
